I applied through a Craigslist posting. They called for an interview. They described the job, asked if I was interested. I said yes and they told me where and when to show up. When you showed up to the meet spot, they drove you to the site for a week of work. If through the week you didn't meet their requirements they would put you on a bus or drive you back home. If you did alright they would call or email you again the following week to go back out to work.
